Recurrent prosthetic valve endocarditis caused by Staphylococcus aureus colonizing skin lesions in severe atopic dermatitis

Abstract

Infective endocarditis, a serious infection most commonly affecting rheumatic or prosthetic valves, generally occurs after bacteremia. Atopic dermatitis, a very common disease, carries a high prevalence of skin infections, particularly with Staphylococcus aureus. While cutaneous colonization by S. aureus represents an important source of bacteremia, few cases of infective endocarditis arising from the skin lesions of atopic dermatitis have been reported. We describe a patient with recurrent S. aureus prosthetic valve endocarditis developing in this manner. © 2007 The Japanese Society of Internal Medicine.
